摘要： The electrically controllable pressure medium brake comprises an electric pressure means (EP) converter (1) to convert an electrical brake request signal into a brake pressure. By way of an emergency brake valve (1), this brake pressure (in the normal case) and a vehicle load-dependent emergency brake pressure limited by a limiting valve (12) (in an emergency), is fed to the brake cylinder (14). For vehicle load-dependent limitation of the emergency brake pressure, a second EP converter (1a) generates from a vehicle load-dependent, electrical signal a vehicle load-dependent pressure medium pressure, which is stored in a pressure medium reservoir (18) and is fed to the limiting valve (12) in order to control it. The second EP converter (1a) is closed in the currentless state, during a power failure, whereby the vehicle load-dependent pressure medium pressure is preserved and the limiting valve (12) can thus continue to limit the emergency brake pressure as a function of the vehicle load. In another embodiment supplemented by a switching valve, only one EP converter serves to generate both the brake pressure and the vehicle load-dependent pressure medium pressure.

摘要： A hold-back valve for single release air brakes includes a plug valve member in a chamber of a valve body and rotatable between at least two positions to establish paths of different resistance to flow between air inlet and outlet passages in the valve body. The plug has spherical central portion with a flattened surface and the spherical central portion is sealingly engageable with one end of a hollow cylindrical flexible packing surrounding the opening of the air inlet passage to the chamber in the valve body. The rotatable plug has passages therethrough to define two or three different flow paths when particular passages of the plug are connected between the air inlet and outlet of the valve body.
